Natural disasters, a series of events that threaten people's lives and are caused by natural or non-natural factors, can cause environmental damage, property losses, psychological impacts, and casualties. One of the natural disasters that often occur in the research area is landslides, which involve the sudden movement of rock or soil masses and are closely related to scientific processes in landscapes. Landslide natural disasters are inseparable from human behavior factors, such as the increase in the number of people who increase the need for land for settlements, industry, agriculture, etc. This study identified the straightness in controlling the potential for landslides in the Cihaur area and its surroundings, Cianjur Regency, West Java Province, by utilizing the Geographic Information System (GIS) approach combined with automatic lineament extraction techniques. As one of the disaster mitigation efforts, slope stability analysis is fundamental to determine areas prone to landslides and provide guidance in land use planning. The method used in this study includes collecting and analyzing Digital Elevation Model (DEM) data, which is then processed to produce hillsides to identify straightness features or lineaments that may affect slope stability. The automatic extraction technique of lineament is used to detect and map straightness patterns in DEM images. The data obtained from this process were further analyzed to determine the level of density and orientation of the lineament, which was then associated with the stability of the slope in the study area. The results showed a strong correlation between the lineament's density and the slope stability level. Slopes with high lineament density tend to have lower stability, which indicates a greater risk of landslides. In addition, the lineament orientation analysis showed an influence from the local geological structure that contributed to the distribution of landslide risk in the region. The results of this analysis were then used to create a slope stability zoning map, which classifies the research area into stable, moderate, and landslide-prone categories. The resulting zoning map provides essential information for landslide disaster mitigation efforts and serves as a tool for regional planners in determining infrastructure development priorities in disaster-prone areas. In addition, this study shows that using GIS combined with an automatic lineament extraction technique is an effective method for identifying and analyzing geological factors that affect slope stability. This study's findings are expected to significantly contribute to disaster risk reduction in Cianjur Regency and other regions with similar geological conditions. Furthermore, this research opens up opportunities for further development in using GIS technology for geological analysis and disaster mitigation. Applying similar techniques in other areas prone to landslides can help improve resilience to natural disasters and support sustainable development.
